Description

Technical Field

[0001] The invention relates to a forging testing device. Background Art

[0002] Tests on forgings include:

[0003] Geometric shape and size: The external dimensions of general forgings are inspected with measuring tools such as steel rulers, calipers, and templates; forgings with complex shapes can be accurately inspected by scribing.

[0004] Surface quality: If there are cracks, bruises, or folding defects on the surface of the forging, they can generally be detected with the naked eye.

[0005] Internal structure: Check for cracks, inclusions, looseness, and other defects inside the forging. The macroscopic structure of the forging section can be inspected with the naked eye or with a 10-30x magnifying glass. A common method in production is acid etching, which involves cutting a sample from the area of the forging to be inspected and etching it with acid to clearly reveal any macroscopic defects on the cross section, such as forging flow line distribution, cracks, and inclusions.

[0006] Metallographic inspection: This is an inspection method that uses a metallographic microscope to observe the fracture structure of forgings. It can check items such as carbide distribution, grain size and decarburization depth.

[0007] Mechanical properties: Mechanical properties testing mainly includes hardness, tensile strength, and impact toughness. Sometimes, cold bending tests and fatigue tests may also be performed according to part design requirements.

[0008] Chemical composition analysis: Forgings are sampled from the corresponding riser end. Important forgings need to be sampled from both ends of the water and riser in order to understand the degree of segregation. Special parts or defect (and failure) analysis often requires analysis of the content of gas, inclusions and trace impurity elements for quality confirmation or research purposes.

[0009] The surface quality defects of forging parts mainly include surface cracks, folds, lack of meat, errors, insufficient die forging, surface pits, surface bubbles and orange peel surface.

[0010] The surface defects of forgings are mainly detected through manual quality inspection, which has low efficiency, especially for forgings with regular surfaces, such as cubes and cuboids. During the quality inspection process, some surfaces are often missed after rotation, resulting in quality inspection errors.

[0011] Based on the above problems, we designed a forging testing device that can perform rapid surface quality inspection on regular forgings. Summary of the Invention

[0040] See Figure 1 and Figure 2The forging testing device shown includes a control cabinet 1 and a frame 2, which is equipped with a conveyor 3. At the top of the frame 2, a first high-definition camera 4 connected to the control cabinet 1 is installed on both sides of the conveyor 3. A rotating clamping device 5 is provided on both sides of the frame 2. At the top of the frame 2, a bracket 6 is provided on the right side of the rotating clamping device 5. A second high-definition camera 7 is installed through the bracket 6. The second high-definition camera 4 is connected to the control cabinet 1, and the forging to be tested is transported by the conveyor 3. When the forging is transported by the conveyor 3, it passes between the first high-definition cameras 4 on both sides, and the two opposite sides of the forging are photographed. When the forging reaches the position of the two rotating clamping devices 5, the forging is clamped by the rotating clamping device 5. At this time, the conveyor 3 retreats, and the rotating clamping device 5 drives the forging to rotate 360°. During the rotation, it is photographed by the second high-definition camera 7. The images captured by the first high-definition camera 4 and the second high-definition camera 7 are transmitted to the control cabinet 1.

[0041] The control cabinet 1 is equipped with an AI recognition system, which learns and memorizes the surface defects of the forgings. When the conveyor 3 transports the forgings through the first high-definition camera 4, it identifies the two clamped end faces of the forgings. When forging defects are detected on the surface of the forgings, the conveyor 3 retracts, so that the forgings do not need to be clamped by the rotary clamping device 5 and can be directly returned.

[0042] When the forging passes the identification of the first high-definition camera 4 and it is determined that the two opposite end faces have no forging defects, the forging is clamped by the rotary clamping device 5. After clamping is completed, the conveyor 3 retreats and leaves the bottom of the forging. At this time, the rotary clamping device 5 drives the forging to rotate, and the remaining surfaces are photographed and identified by the second high-definition camera 7. The materials with forging defects are returned, and the materials without forging defects are unloaded.

[0043] Depending on the conveying speed of conveyor 3, when the first high-definition camera 4 captures the forged workpiece, the rotary clamping device 5 can be synchronously activated. Depending on the conveying speed of conveyor 3, when the forged workpiece reaches the position of the rotary clamping device 5, conveyor 3 stops conveying. The stopping time is preset by the control cabinet 1 and needs to be sufficient for the rotary clamping device 5 to complete the clamping of the forged workpiece. This operation method can shorten the idle running time of the rotary clamping device 5, thereby improving testing efficiency.

[0044] See Figures 3 to 6As shown, the conveyor 3 includes a pulley roller 31, a movable roller 32, a transition roller 33, a tensioning roller 34, a drive motor 35 and a conveyor belt 36. The pulley roller 31 is provided with multiple parallel rollers on the upper and lower sides. The pulley roller 31 is rotatably matched with the frame 2. The drive motor 35 is installed on the outside of the frame 2 and is connected to drive the pulley roller 31 on the outer side. Sliders 37 are provided at both ends of the movable roller 32. The slider 37 is rotatably matched with the movable roller 32. A slide groove 21 is processed on the groove wall of the frame 2. A screw 38 is rotatably matched in the slide groove 21. One end of the screw 38 is provided with a first drive motor 39. The screw 38 is threadedly matched with the slider 7. The first drive motors 39 on both sides are started synchronously. The drive motor 35 and the first drive motor 39 are both connected to the control cabinet 1; the tensioning roller 34 is provided with a plurality of parallel rollers on the upper and lower sides. The two ends of the tensioning roller 34 are provided with second sliders 310, and the second sliders 310 are rotatably matched with the tensioning roller 34. Grooves 22 are provided at the groove walls on both sides of the frame 2, and a guide rod 23 is vertically provided in the groove 22. The second slider 310 slides and fits in the groove 22, and the guide rod 23 passes through the second slider 310. A spring 24 is provided on the guide rod 23, and the spring 24 acts on the top of the second slider 310. Under the action of the spring 24 and gravity, the second slider 310 moves downward; the transition roller 33 is provided with two, which are respectively arranged on both sides of the tensioning roller 34. The conveyor belt 36 is rotationally supported by the pulley roller 31 and the movable roller 32. The tensioning roller 34 acts on the inner bottom of the conveyor belt 36, and the transition roller 33 is rotatably supported on the outside of the conveyor belt 36.

[0045] In the above technical solution, the screw 38 is driven to rotate by the first drive motor 39 to adjust the position of the movable roller 32. During the adjustment process, the spring 24 provides tension to ensure that the conveyor belt 36 is always in a tensioned state.

[0046] The upper surface of the conveyor belt 36 is always flat. The forging is transported to the position of the rotary clamping device 5 by the conveyor belt 36. After delivery, the forging is clamped by the rotary clamping devices 5 on both sides, and then the conveyor belt 36 retracts to the initial position to avoid interfering with the rotation of the forging. After retraction, the conveyor belt 36 is kept rotating to start the transportation of the next forging to be tested.

[0047] See Figure 7As shown, a vertical plate 25 is provided inside the frame 2, and the height of the upper end surface of the vertical plate 25 is lower than the height of the transition roller 33 on the right side, so that the vertical plate 25 is always out of contact with the conveyor belt 36, and the tensioning roller 34 does not exceed the vertical plate 25 when it moves to the extreme position to the left, so that after the tensioning roller 34 retracts and the conveyor belt 36 continues to convey, the forgings located on the surface of the conveyor belt 36 fall to the right side of the vertical plate 25.

[0048] In the above technical solution, the vertical plate 25 is used to block the forgings, so as to prevent the forgings from falling into the left side of the vertical plate 25 and affecting the normal operation of the equipment.

[0049] See Figure 3 、 Figure 4 and Figure 7 As shown, a first vertical plate 26 is provided inside the frame 2, and the first vertical plate 26 is located on the right side of the vertical plate 25. An inclined plate 27 is welded between the vertical plate 25 and the first vertical plate 26. A material return port 28 is provided at the rear of the frame 2, and the inclined plate 27 is inclined downward toward the material return port 28. The forgings dropped from the conveyor belt 36 pass through the inclined plate 27 and exit from the material return port 28; a first transverse groove 29 and a second transverse groove 210 are provided on the inner walls on both sides of the frame 2, and the height of the second transverse groove 210 is lower than the height of the first transverse groove 29, and the first transverse groove 29 extends to the top of the material return port 28. A stripper plate 8 is provided in the frame 2, and the stripper plate 8 is inclined, and the height of the left end of the stripper plate 8 is higher than At the right end, pulleys 81 are provided at the front and rear end faces of the unloading plate 8, and the pulleys 81 are engaged in the first transverse groove 29. Slide rods 82 are provided at the front and rear end faces of the unloading plate 8, and the slide rods 82 are engaged in the second transverse groove 210. A pneumatic push rod 83 is installed on the outside of the frame 2, and the pneumatic push rod 83 is connected to the slide rod 82 at one end. When the pneumatic push rod 83 retracts to the extreme position, the unloading plate 8 moves to the bottom of the conveyor belt 36. At this time, the position of the conveyor belt 36 retreats, and when conveying continues, the forgings on the surface of the conveyor belt 36 fall onto the unloading plate 8 and are guided to the right through the unloading plate 8. The pneumatic push rod 83 is connected to the control cabinet 1; a scraper 888 is provided at the top position of the left end of the unloading plate 8.

[0050] In the above technical solution, a material return bin is formed by the cooperation of the vertical plate 25 and the first vertical plate 26. The forgings that fail the quality inspection of the first high-definition camera 4 and the second high-definition camera 7 fall between the vertical plate 25 and the first vertical plate 26, and exit from the material return port 28 after passing through the inclined plate 27 for manual re-inspection.

[0051] The workpiece that has passed the quality inspection of the first high-definition camera 4 and the second high-definition camera 7 falls onto the unloading plate 8 under the retraction of the pneumatic push rod 83 and is discharged from another position along the unloading plate 8.

[0052] After receiving the forged piece, the stripper plate 8 is quickly withdrawn by the pneumatic push rod 8 and driven by the scraper bar 888 to slide the forged piece out along the stripper plate 8 .

[0053] See Figure 3 As shown, an opening 232 is provided on the right side of the frame 2 .

[0054] A trolley can be pushed into the opening 232 so that the forged parts discharged through the unloading plate 8 can be directly collected for easy transportation.

[0055] See Figure 7 As shown, the height of the first vertical plate 26 is lower than that of the vertical plate 25 . When the stripper plate 8 slides to the left to the limit position, its lower surface never contacts the upper end surface of the first vertical plate 26 .

[0056] The above techniques are mainly used to avoid motion interference.

[0057] See Figure 8 As shown, the rotary clamping device 5 includes a side bracket 51, an electric push rod 52, a rotary motor 53 and a buffer device 54. The side bracket 51 is fixed to the outside of the frame 2, the electric push rod 52 is installed through the side bracket 51, the buffer device 54 is installed at the movable end of the electric push rod 52, the rotary motor 53 is installed through the buffer device 54, and a clamping plate 55 is installed at the turntable position of the rotary motor 53. The forging to be tested is clamped by the clamping plates 55 on both sides. The electric push rod 52 and the rotary motor 53 are both connected to the control cabinet 1.

[0058] In the above technical solution, the electric push rod 52 is pushed out to make the clamping plate 55 contact with the forging. After the contact, the electric push rod 52 continues to push out until the pushing torque of the electric push rod 52 reaches the set value. The set value is set by the control cabinet 1 and is determined according to the weight of the forging. At this time, the contact pressure between the clamping plate 55 and the forging is sufficient. Under the clamping of the clamping plates 55 on both sides, it can be ensured that the forging will not fall.

[0059] The buffer device 54 is provided to prevent the rotary motor 53 from being subjected to excessive impact due to direct compaction of the clamping plate 55 , thereby protecting the rotary motor 53 .

[0060] See Figure 8 and Figure 9As shown, the buffer device 54 includes a sleeve 541, and an end cover 542 is detachably provided at the opening of the sleeve 541. A guide hole 543 is provided at the axis center of the end cover 542, and a guide block 544 is provided at the hole wall of the guide hole 543. A guide rod 545 is installed through the guide hole 543, and the guide rod 545 has a guide groove 546 that cooperates with the guide block 544. The guide groove 546 passes through the guide rod 545 backward, and the end of the guide rod 545 located in the sleeve 541 is provided with a pressure plate 547, and a first spring 548 is provided in the sleeve 541. The first spring 548 acts on the pressure plate 547, and the outer end of the guide rod 545 is fixedly connected to the rotary motor 53.

[0061] In the above technical solution, the gradual compression of the first spring 548 gradually increases the contact pressure between the clamping plate 55 and the forging. The compression of the first spring 548 can absorb the impact force at the moment of contact with the forging, thereby protecting the rotary motor 53.

[0062] See Figure 9 As shown, a non-slip rubber ring 5551 is provided on the surface of the clamping plate 55 , and an exhaust hole 5552 is penetrated through the inner wall of the clamping plate 55 .

[0063] The hard rubber of rubber ring 5551 has a rough surface to increase the contact friction with the forging.

[0064] The provision of the exhaust holes 5552 can prevent the clamping plate 55 and the forging from being adsorbed by negative pressure.

[0065] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
